The approach, which they call Quantum-Secure Authentication (QSA), centers on single particles of light, or photons, and their ability to encode data so that attackers cannot determine what the information is. It exploits a property of photons that allows them to effectively be in multiple places at once, a phenomenon described in quantum physics.
Researchers in the Netherlands are applying quantum physics in an attempt to create fraud-proof credit cards and ID cards.
“Quantum-physical principles forbid an attacker to fully characterize the incident light pulse,” the researchers wrote in an article in the journal Optica. “Therefore, he cannot emulate the key by digitally constructing the expected optical response, even if all information about the key is publicly known.”
The researchers at the University of Twente and Eindhoven University of Technology coated a credit card with a thin layer of white paint containing millions of nanoparticles. When light hits the nanoparticles, it bounces around until it escapes, creating a unique pattern that depends on the precise position of the particles in the paint. The card is “enrolled” in the system by recording the way that it reflects light.
To authenticate the card, a bank machine showers the paint with a pulse of light that is unique to each transaction. When the correct tell-tale pattern of light emerges as an “answer” to the bank’s “question,” the card can be authenticated.
While an attacker could measure the entire incoming light pattern and then use a projector to return the correct answer, the ability of photons to be in multiple places at once allows the bank to create the complex light question with only a small number of photons, or even just one. Due to the characteristics of quantum physics, an attempt to observe the question and answer process between a reader and the card would destroy the information in the transmission, making it more secure.
“Even if somebody has the full information of how the card is built, technology does not allow him to build a copy,” lead author Pepijn Pinkse of the University of Twente said via email. “The nanoparticles are too small and there are too many of them which need to be positioned with too high accuracy.”
The approach could be used in everything from authenticating passports to opening electronic locks on car doors or accessing secure areas such as government buildings.
T-Mobile has announced a monthly data rollover plan for consumers and business customers called “Data Stash,” but the plan still will not allow workers to share their data with others in a work group.
Data Stash works much the same way for users who have a Simple Choice plan (or Simple Choice for Business Value Plan) and have purchased 3GB or more of LTE data per month for smartphones and 1GB or more for tablets.
T-Mobile will give those existing customers, as well as new customers, 10GB of free LTE data in January. The data must be used by the end of 2015, and once it’s gone, each month of unused data in a plan can be rolled over monhtly for up to a year.
T-Mobile CEO John Legere described data rollover as a high priority for customers, noting that they asked on Twitter in 2014 more than 40,000 times for such a program. And Legere bashed rivals like AT&T and Verizon Wireless who don’t offer such a program, contending that $50 billion annually is lost by wireless customers who have paid for data but then see it disappear at the end of the month when it doesn’t roll over.
“We’re putting an end to this appalling industry practice today,” he said.
Even so, Data Stash won’t let workers share their data allotments with other workers in a group, as T-Mobile describes on its Web site: “Our data plans are specific to the person, so businesses aren’t wasting time and effort tracking everyone’s usage. In other words, this is not a shared data option.”
Dell has merged its SonicPoints with Dell SonicWALL next-generation firewalls to create what it claims are secure wireless networks. According to the company, the Dell SonicWALL firewalls automatically detects and provision SonicPoints, while it pushes appropriate security updates as well as policies to ensure enterprise-class security.
Of course, it also claims to simplify management, deliver a lower TCO and protect you from badgers at the same time. But it is a pretty interesting product. The SonicPoint AC Series of wireless access points would be able to support the high-performance IEEE 802.11ac wireless standard in order to offer close to three times that of the last wireless standard (802.11n).
SonicPoints will offer deep packet inspection security from Dell SonicWALL next-generation firewalls. This opens the door for small- and mid-sized organizations to leverage enterprise-class wireless performance and security, all the while simplifying wireless network setup and management.
With enterprise-level performance, WiFi-ready devices are able to hook up from greater distances, while making use of bandwidth-intensive mobile apps, including video and voice, working in higher-density environments with virtually no signal degradation.
Stanford University researchers have developed a multi-layered “high-rise” chip that could significantly outperform traditional computer chips, taking on the hefty workloads that will be needed for the Internet of Things and big data.
Utilizing nanotechnology, the new chips are built with layers of processing on top of layers of memory, greatly cutting down on the time and energy typically needed to move information from memory to processing and back.
Max Shulaker, a researcher on the project and a Ph.D candidate in Stanford’s Department of Electrical Engineering, said they have built a four-layer chip but he could easily see them building a 100-layer chip if that was needed.
“The slowest part of any computer is sending information back and forth from the memory to the processor and back to the memory. That takes a lot of time and lot of energy,” Shulaker told Computerworld. “If you look at where the new exciting apps are, it’s with big data… For these sorts of new applications, we need to find a way to handle this big data.”
The conventional separation of memory and logic is not well-suited for these types of heavy workloads. With traditional chip design, information is passed from the memory to the processor for computing, and then it goes back to the memory to be saved again.
In relative terms, that takes a lot of energy and time – way more than the computation itself.
“People talk about the Internet of Things, where we’re going to have millions and trillions of sensors beaming information all around,” said Shulaker. “You can beam all the data to the cloud to organize all the data there, but that’s a huge data deluge. You need [a chip] that can process on all this data… You want to make sense of this data before you send it off to the cloud.”
The researchers, led by Subhasish Mitra, a Stanford associate professor of electrical engineering and computer science, and H.S. Philip Wong, a professor in Stanford’s school of engineering, used carbon nanotube transistors instead of silicon and replaced typical memory with resistive random-access memory (RRAM) or spin-transfer torque magnetic random-access memory (STT-RAM). Both use less power and are more efficient than traditional memory systems.
Chinese smartphone maker Coolpad has created an extensive “backdoor” into its Android devices that can track users, serve them unwanted advertisements and install unauthorized apps, a U.S. security firm alleged today.
In a research paper released today, Palo Alto Networks detailed its investigation of the backdoor, which it dubbed “CoolReaper.”
“Coolpad has built a backdoor that goes beyond the usual data collection,” said Ryan Olson, director of intelligence at Palo Alto’s Unit 42. “This is way beyond what one malicious insider could have done.”
Coolpad, which sells smartphones under several brand names — including Halo, also called Danzen — is one of China’s largest ODMs (original device manufacturers). According to IDC, it ranked fifth in China in the third quarter, with 8.4% of the market, and has expanded sales outside of the People’s Republic of China (PRC) and Taiwan to Southeast Asia, the U.S. and Western Europe.
Tipped off by a string of complaints from Coolpad smartphone users in China and Taiwan — who griped about seeing advertisements pop up and apps suddenly appear — Palo Alto dug into the ROM updates that Coolpad offered on its support site and found widespread evidence of CoolReaper.
Of the 77 ROMs that Palo Alto examined, 64 contained CoolReaper, including 41 hosted by Coolpad and signed with its own digital certificate.
Other evidence that Coolpad was the creator of the backdoor, said Olson, included the malware’s command-and-control servers — which were registered to domains belonging to the Chinese company and used, in fact, for its public cloud — and an administrative console that other researchers had found last month because of a vulnerability in Coolpad’s backend control system. The console confirmed CoolReaper’s functionality.
British chip designer ARM could cash in on the mobile industry’s rush to transition to 64-bit operating systems and hardware.
Canaccord Genuity analyst Matt Ramsey argues that ARM is still a ‘Buy’ stock, as it’s trading at $43, while his price target is $54 to $56. Ramsay is upbeat for a number of reasons and the 64-bit craze is one o them.
He pointed out that sales of ARMv8 chips are raping up and are no longer limited to Apple. Qualcomm’s upcoming Snapdragon 810 is also based on ARMv8, along with all other upcoming 64-bit SoCs. Ramsey named Qualcomm, MediaTek and Samsung as the three biggest contributors to ARM’s 64-bit business.
In addition to smartphones, ARMv8 designs are finding their way into enterprise networks and servers, creating even more opportunities. This is good news for ARM, as its royalties for processor designs based on the ARMv8 instruction set are significantly higher than for venerable 32-bit parts.
Android apps really take advantage of those permissions they ask for to access users’ personal information: one online store records a phone’s location up to 10 times a minute, French researchers have found. The tools to manage such access are limited, and inadequate given how much information phones can gather.
In a recent study, ten volunteers used Android phones that tracked app behavior using a monitoring app, Mobilitics, developed by the French National Institute for Informatics Research (INRIA) in conjunction with the National Commission on Computing and Liberty (CNIL). Mobilitics recorded every time another app accessed an item of personal data — the phone’s location, an identifier, photos, messages and so on — and whether it was subsequently transmitted to an external server. The log of the apps’ personal information use was stored on the phone and downloaded at the end of the three months for analysis.
The volunteers were encouraged to use the phones as if they were their own, and together used 121 apps over the period from July to September. A similar study last year used a special iOS app to examine the way iPhone apps access users’ personal data.
Many apps access phones’ identifying characteristics to track their users, the researchers said. One of the few options users have to avoid this tracking is a switch in the “Google Settings” app to reset their phone’s advertising ID. That’s not much help, though, as apps have other ways to identify users. Almost two-thirds of apps studied in the three-month real-world test accessed at least one mobile phone identifier, a quarter of them at least two identifiers, and a sixth three or more. That allows the apps to build up profiles of their users for advertising purposes.
Location was one of the most frequently-accessed items of data. It accounted for 30 percent of all accesses to personal information during the test, and 30 percent of the apps studied accessed it at some point. The Facebook app recorded one volunteer’s location 150,000 times during the three-month period — more than once per minute, on average, while the Google Play Store tracked another user ten times per minute at times. Often, the only use apps make of such information is to serve personalized advertising, as was the case with one game that recorded a user’s location 3,000 times during the study.
South Korea’s LG Electronics Inc will roll out a new range of high-tech TVs in early 2015, expanding its line-up while it strives to cut costs that make its prized light-emitting diode (OLED) sets too expensive for most consumers.
A spokesman for the world’s No. 2 TV maker after domestic rival Samsung Electronics Co Ltd said on Tuesday LG will start selling products using quantum dot technology early next year. He didn’t disclose details including pricing.
The technology incorporates a film of tiny light-emitting crystals into regular liquid crystal displays (LCD), boosting picture quality. LG will have 55-inch and 65-inch ultra-high definition quantum dot TVs on display at the major CES trade show next month in Las Vegas.
Japan’s Sony Corp is so far the only major TV maker selling quantum dot models.
LG was widely expected to launch quantum dot TVs next year, having declared its intention to use the products in a dual-track strategy as the firm and its affiliate LG Display Co Ltd try to push OLED prices down. Analysts say it may take the LG firms several years to meet that goal.
The OLED TV sets remain expensive: a 65-inch ultra-high definition model launched in Korea earlier this year was priced at 12 million won ($10,993). A comparable Sony quantum dot TV costs about $3,799, according to the Japanese firm’s website.
Samsung Electronics has said quantum dot is one of many technologies it is considering. Analysts expect Samsung Electronics to launch quantum dot TVs next year, and believe it could be more aggressive in pushing the products than LG, which remains committed to OLED.
The LG spokesman said Dow Chemical Co is supplying quantum dot material. Dow Chemical confirmed the supplier relationship in an emailed statement.
Dow is building a quantum dot factory in South Korea using technology from partner Nanoco Group Plc, with production starting in the first half of 2015.
The FCC voted last Thursday to update its rules for the Connect America Fund, the broadband subsidy program funded through fees on telephone service, with a major change being the increase in minimum download speeds from 4Mbps to 10Mbps from fixed broadband providers.
Broadband providers AT&T and Verizon had opposed the speed increase, and one of the FCC’s Republican commissioners questioned whether the new speed requirement could limit deployment.
The new speed requirements could double the cost of deployment to rural areas, but the commission did not also double the time that broadband providers could complete their deployments, Commissioner Ajit Pai said.
Instead of increasing the funding window for deployments from five to 10 years, as dozens of members of Congress had requested, the commission increased funding term to six years in most cases. Adding new speed requirements without allowing much more time for broadband providers to receive funding may discourage broadband providers from participating, Pai said.
“I fear we are going to leave many communities without broadband for the foreseeable future,” Pai said. “Incentivizing wireline broadband providers to deploy service deep into the unserved countryside requires a balance act. Today’s order disrupts that balance.”
But FCC Chairman Tom Wheeler said the agency doesn’t want to pay for “second-class broadband service.” If large broadband providers don’t agree with the terms of the subsidy, the FCC will use an auction to bring service to rural areas, he said.
“While the Internet of Things (IoT) conjures a vision of ‘anytime, any place’ connectivity for all things, the realization is complex given the need to work across interconnected and heterogeneous systems, and the special considerations needed for security, privacy, and safety,” co-wrote Google chief Internet evangelist Vint Cerf, in a blog post announcing the research program.
The ”Internet of Things” is technical shorthand describing what is expected to be a mass wave of portable devices and sensors that will gather information and send it over the Internet for purposes of analysis and monitoring. Over 50 billion things will be connected to the Internet by 2020, Cisco has estimated.
Google plans to issue two sets of awards, both meant to fuel work to be carried out over a year.
One set of grants will be for larger team projects that Google will pay between $500,000 and $800,000 to see completed. Google expects that the work could be undertaken either by an academician leading a team of researchers or by a graduate student “willing to dedicate a substantial portion of their research time to this expedition,” according to Google’s request for proposals document.
A smaller set of grants, ranging from $50,000 to $150,000, will also be given out. For these grants, Google is looking for “new and unorthodox solutions” in user interface and application development, in privacy and security, and in systems and protocols research, according to the blog post.
A company insider has spilled the beans in Korea, claiming that Samsung has started Apple A9 production in 14nm FinFET.
The A9 is the next generation SoC for Apple iPhone and iPad products and it is manufactured on the Samsung – GlobalFoundries 14nm FinFET manufacturing process. In the other news, Samsung’s Ki-nam, president of the company’s semiconductor business and head of System LSI business has confirmed that the company started production of 14-nanometre FinFET chips.
The report mentions Austin as a possible site for Apple products but we wonder if the GlobalFoundries Fab 8 in New York State could become one of the partners for the 14nm FinFET manufacturing. Samsung didn’t officially reveal the client for the 14nm FinFET, but Apple is the most obvious candidate, while we expect to see 14 / 16nm FinFET graphics chips from AMD and Nvidia but most likely in the latter half of 2015 at best.
Qualcomm is likely to announce new LTE modem based on 14nm FinFET and the flagship SoC Snapdragon 810 is a 20nm chip. Qualcomm is manufacturing its 810 chips as we speak to meet demand for flagship Android phones coming in Q1 2015. Flagship Samsung, HTC and LG phones among others are likely to use Snapdragon 810 as a replacement for this year’s Snapdragon 801, a high end chip that ended up in millions of high-end phones.
Samsung / GlobalFoundries14nm FinFET process is 15 percent smaller, 20 percent faster, and 35 percent more power efficient compared to 20nm processors. This definitely sounds exiting and will bring more performance into phones, tablets, GPUs and will significantly decrease power consumption. The move from 28nm is long overdue.
We believe that Qualcomm’s LTE modem might be the first chip to officially come with this manufacturing process and Apple will probably take most of the 14nm production for an update in its tablets and phones scheduled for 2015.
Intel showed off a new platform which it claims makes it easier for companies to create Internet-connected smart products using its chips, security and software.
Intel’s platform is like Lego and based on the chipmaker’s components and software for companies to create smart, connected devices. The only difference is that you can’t enact your own Doctor Who scene from it.
Doug Davis, head of Intel’s Internet of Things business, said at a launch event in San Francisco it will make it a doddle to connect to data centres in order analyse data collected from devices’ sensors.
Intel’s chips should compute capability in end-point devices that scale from its highest performance Xeon processor to the Quark family of products.
Intel’s Internet of Things Group had $530 million in revenue in the September quarter. That accounted for just 4 percent of Intel’s total revenue in the quarter, but it grew 14 percent over the previous year, which was faster than the company’s PC business.
Dell, SAP, Tata Consultancy, Accenture and other companies are working with the new reference model, Davis said.
Instagram, which launched in 2010, edged past 8-year-old Twitter and its reported 284 million monthly active users.
Facebook, which bought Instagram in 2012 for $1 billion, has nothing to worry about. In September, the social network reported that its own active monthly user base had hit 1.35 billion.
“Over the past four years, what began as two friends with a dream has grown into a global community that shares more than 70 million photos and videos each day,” wrote Instagram CEO Kevin Systrom in a blog post. “We’re thrilled to watch this community thrive and witness the amazing connections people make over shared passions and journeys.”
Zeus Kerravala, an analyst with ZK Research, said Instagram’s impressive growth stems from its popularity with millennials, who have a strong connection with social networking, selfies and images.
“The younger generation, in particular, is a very visually oriented group that loves selfies,” Kerravala said. “Pictures just say more — they’re fast and easy. Instead of saying, ‘What a great view of the Grand Canyon,’ snap a photo and upload it.”
He noted that Twitter users can upload photos and short videos to the micro-blogging site, but the site is mainly used for its 140-character or less messages.
“I think Twitter is more for information dissemination, where Instagram is more about sharing content,” Kerravala said.
Chief Operating Officer Kevin Turner told Japanese news service Nikkei on Wednesday that the new system would be released “early next fall.”
Microsoft has not publicly set a firm timetable for the release of Windows 10, but only last week suggested the possibility of an earlier release.
“By next late summer and early fall we’ll be able to bring out this particular OS (operating system). That’s the current plan of record,” Turner told the Credit Suisse Technology Conference last Thursday.
An autumn release would put Windows 10 on track for launch three years after Windows 8, which got a mixed reception as it confused many traditional PC users with a design more suited to tablets.
Microsoft unveiled the name Windows 10 in late September, saying the jump in numbers from 8 to 10 marked a leap as it looks to unify the way people work on tablets, phones and traditional computers.
An early test version of Windows 10 – which blends the traditional look and much-loved start menu with newer features – has been available for download from Microsoft’s website for more than two months.
Windows is still a core part of Microsoft’s business and dominates the desktop computing market with 1.5 billion users. But the growth of smartphones and tablets means Windows now runs on only about 14 percent of computing devices worldwide, according to tech research firm Gartner.
Ericsson has thrown a spanner into Chinese firm Xiaomi’s expansion plans, and has reportedly stopped it from selling handsets in India.
According to reports, this is already happening. We have asked Ericsson to confirm its role and what it wants to say about it. It told us that the reports are true and that it is ready to defend itself.
“It is unfair for Xiaomi to benefit from our substantial R&D investment without paying a reasonable licensee fee for our technology. After more than 3 years of attempts to engage in a licensing conversation in good faith for products compliant with the GSM, EDGE, and UMTS/WCDMA standards, Xiaomi continues to refuse to respond in any way regarding a fair license to Ericsson’s intellectual property on fair, reasonable and non-discriminatory (FRAND) terms,” it said in a statement.
“Ericsson, as a last resort, had to take legal action. To continue investing in research and enabling the development of new ideas, new standards and new platforms to the industry, we must obtain a fair return on our R&D investments. We look forward to working with Xiaomi to reach a mutually fair and reasonable conclusion, just as we do with all of our licensees.”
Xiaomi has responded to Bloomberg but it declined to say too much until it has access too all of the information.
“Our legal team is currently evaluating the situation based on the information we have,” said the spokesperson. “India is a very important market for Xiaomi and we will respond promptly as needed and in full compliance with India laws.”
The banning on the sale of devices was approved by a court in Delhi India, according to reports, and is based on an Ericsson claim on eight patents that it owns.
Xiaomi has bold plans for its own future and sees itself competing against rivals like Samsung and Apple. It has given itself between five and 10 years to do this, and will presumably want to include the Indian market in those plans.
